METALLlC FENCE.

SPECIFICATION forming part of Letters Patent No. 272,482, dated February 20, 41883.

Application alea .uiy 18,1882. (No model.)

To all whom it may concern;

Beit known that I, CHARLES H. SALISBURY, of De Kalb, inthe county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Metallic Fences, of which the following is a specification.

My invention relates to improvements in metallic fencing; and the same consists in al barbed fence-rail composed of thin strips of sheet metal having their edges folded and locked together in such manner as to break joints, so as to form a compound rail of sufficient thickness to give the requisite strength, and provided with sharp points orbarbs on its outer edge, the different strips being united together by solder or cement.

In the accompanying drawings, which form apart of this specification, andin which similar letters of reference indicate like parts, Figure 1 is a plan view of my improved metallic t'encing. Fig. 2 is an' edge view; and Figs. 3 and 4 are cross-sections on lines .fr or and y y, re-

spectively, of Fig. 1.

In the drawings, A represents the fencerai'l, which is composed ot two narrow strips of sheet metal, a and c', each of which has one straight or smooth and one serrated or4 toothed edge, the4 smooth edges of the two strips being folded and interlocked together, so as to form four thicknesses of the sheet metal in the central part of the' rail, and the serrated edges having part of the teeth turned at right angles to the others, so as. to present barbs or pointsin four different directions, when the twostripsare interlocked together. The sheet-metal strips ct a may be cut fromA sheet metal of the ordinary width, the different short sections being joined together, so as to lap' joints, and the separate strips and folds being united throughout their whole length by solder, so as to form a solid rail. The joints c, between theseparate strips, instead of being square joints, as shown, may preferably be cut diagonal or splicing, or the ends of the strips may be lapped over each other, as thereby greater strength will be afforded.

= In cutting the strips from the sheet-'metal blank each alternate cut is serrated and the other straight, so that there is no loss of material, and then thesmooth edge ofthe strips is folded upon itself and a portion of the teeth of the serrated edge turned at right angles to the others, and the folded edges of the strips are then interlocked together, care being taken to break joints, when the compound rail thus formed is passed through agalvanizing-bath, whereby the whole is tirmly united and soldered together. In this way a very strong and effective barbed fence-rail may be easily made from sheet-iron alone, 'which is comparatively cheap material, and at the same time the fence-rail produced will be of sufficient size to be easily discernible by stock, and thus obviate thev danger thereto incident to the use of most barb fence heretofore made.

I claim.-

The improved barbed metallic fence-rail composed of short strips of sheet metal provided with interlocked folded straight edges and serrated' outer edges with teeth turned in ditferent directions, said strips being united together so as to break joints, and soldered,

substantially as specified.
